I enjoy making the bridges of my starships unique, but it's annoying that I can't customize the other key areas of each starship.
I'd like to make the colors of the ship hallways match the bridge.
I'd like to be able to install a warpcore that looks different than the same one in every ship ... and I'd like to change the size of main engineering depending on the type of ship (small Defiant-style escorts shouldn't have giant engine rooms from Sovereign-class ships).
Likewise, let me customize the ship's lounge, sickbay, and transporter room.
